THE GEOLOGIST. 



Elementary substances, minerals, plants, and animals of all grades are here 

 carefully classified ; and the geologic series of phenomena are tabulated with the 

 latest corrections. 



We fully coincide with the author in his prefatory remarks, that such a hand- 

 book as this is greatly needed ; that technicalities must exist in a new science, 

 to express new objects and new facts; that in this book the ordinary reader 

 referrmg to it will generally find the information he requires in the first 

 and second sentences of a definition ; and that the student, the miner, the en- 

 gineer, the architect, the agriculturist, and others, will find much that is use- 

 ful to them in the longer descriptions and explanations. 



The book is well printed, with good clear type, and is remarkably free from 

 errors : an advantage doubtless arising from the fact that the work is from the 

 hands of an author who knows his subject, takes a pleasure in it, and conscien- 

 tiously bestows upon it plenty of time. We hope he will soon have occasion 

 to produce a second and enlarged edition. 



Elementary Geological Collections ; and Geological and Entomological Cabinets. 

 Issued by the Naturalists' Association poe, the Advancement of 

 Science, 17, Dean-street, Soho, London. 



No. 47. — Small box with lifting trays containing a collection of ninety speci- 

 mens of minerals classified and arranged according to their chemical bases. 

 No. 48. — The like collection bound in two volumes. 



No. 15. — Geological Collection of Rocks and Possils, containing about 120 

 specimens illustrative of the Palaeozoic, Mesozoic, Cainozoic, the Igneous and 

 Volcanic rocks. 



Cabinet No. 10, — Containing six drawers for Entomological, Geological, or 

 other collections. 



We inspected these cabinets and the selections of minerals, rocks, and fossils 

 with much pleasure, because pains have been taken to get them up tastefully, 

 cheaply, and well. The specimens of even the smaller elementary collections are 

 sufficiently large to display the general characters of the objects. The geolo- 

 gical collection of rocks. No. 15, is formed of pieces almost large enough to be 

 termed hand-specimens ; while the common typical fossils with which these 

 are interspersed give additional value and interest to the series. 



The small cabinet. No. 10, is a very tasteful affair. The door and the 

 drawers being veneered, it presents quite a drawing-room appearance. It is 

 well adapted for small collections of insects, or very select fossils, and is one of 

 a series of cheap cabinets, which wiU supply a long-desired want amongst ama- 

 teur naturahsts. 



In one instance, in No. 48, we detected two wrong minerals ; but this is ap- 

 parently only a misplacement in their respective spaces of Oxide of Manganese 

 and OHgist Iron, as in the same collection bound in book-like cases, these minerals 

 are correctly placed. In the list of strata the granite and some other rocks are 

 (contrary_ to some classifications) very properly and correctly grouped together 

 with the intrusive rocks. 



Altogether these selections are very creditable and very fairly reliable.
